1/24. Papillary serous carcinoma of the tunica vaginalis testis.This is a case report of a testicular papillary serous carcinoma of ovarian type (PSCOT) diagnosed in a 50-year-old man. The tumor presented in the form of multiple papillary exophytic excrescencies on the visceral tunica vaginalis testis lining the inner surface of a hydrocele sac. The tumor was histologically a papillary serous carcinoma with numerous psammoma bodies, indistinguishable from similar tumors arising on the surface of the ovary. Following the tumor's surgical removal, the patient was treated with the same drugs used to treat ovarian serous carcinomas, and he is alive two years after the initial diagnosis. PSCOT must be distinguished from mesothelioma of the tunica vaginalis testis, a tumor with a most unfavorable prognosis. As shown here, immunohistochemical findings can be useful for formulating the correct diagnosis of PSCOT.- - - - - - - - - - ranking = 1keywords = tunica (Clic here for more details about this article) |
2/24. Metastatic tumour of the tunica vaginalis testis from carcinoma of the stomach.A 50-year-old man with advanced inoperable gastric adenocarcinoma and diffuse peritoneal metastasis received six cycles of palliative chemotherapy and responded clinically with weight gain. Two months after the completion of chemotherapy, however, he developed a left hydrocele. Aspiration yielded 70 ml of yellowish hydrocele fluid, which contained metastatic adenocarcinoma cells, consistent with a gastric primary tumour. A diagnosis of malignant hydrocele was made. Two weeks later, he developed a painful recurrent left hydrocele with increasing pain and swelling. Left orchidectomy was performed. Tiny white mural nodules measuring 1 mm in size were noted on the tunica vaginalis. No focal lesion was noted in the testis. On microscopic examination, the tunica vaginalis showed reactive mesothelial hyperplasia and extensive lymphatic permeation by poorly differentiated adenocarcinoma, consistent with a gastric primary tumour.- - - - - - - - - - ranking = 1keywords = tunica (Clic here for more details about this article) |
3/24. Prenatal testicular torsion: sonographic appearance in the newborn infant.The prenatal diagnosis of spermatic cord torsion is often really difficult and the diagnosis is usually retrospective. Herein, we report a case of a male newborn baby who presented at delivery with an enlarged, swollen and tender scrotum. US showed an enlarged right testis, with dishomogeneous texture, fluid collection between the testis and the tunica vaginalis and large hydrocele. Differential diagnosis included hydrocele complicated by infection or hemorrhage, testicular tumor or postnatal testicular torsion. color and power Doppler did not reveal any flow signal, and the diagnosis of antenatal torsion with initial necrosis was made. The role of color Doppler US is emphasized in directing the patient to emergency surgical exploration, when testicular salvage may be possible. Delayed surgical treatment can be proposed, when the diagnosis of antenatal torsion has a high degree of certainty. However, the Doppler examination of a newborn baby's testis is a very difficult challenge even for an experienced radiologist.- - - - - - - - - - ranking = 0.16666666666667keywords = tunica (Clic here for more details about this article) |
4/24. Diagnosis of malignant mesothelioma of the tunica vaginalis testis by ultrasound-guided fine-needle aspiration.Malignant mesothelioma of the tunica vaginalis testis is a very rare tumor that is not usually diagnosed until surgery is undertaken. In only a few cases has the correct diagnosis been obtained preoperatively by cytologic examination of fluid from the hydrocele. We describe a case of mesothelioma of the tunica vaginalis testis that was suspected on sonography because of the presence of a hydrocele and focal nodularities. The diagnosis was confirmed preoperatively by ultrasound-guided fine-needle aspiration cytology aimed at 1 of the focal nodularities. Our patient was an 85-year-old man with concomitant cancer of the sigmoid colon; because of his age and the spread of his colon cancer, we did not remove the scrotal lesion. We recommend consideration of ultrasound-guided fine-needle aspiration cytology of the solid masses instead of the fluid from the hydrocele in cases of suspected malignant mesothelioma of the tunica vaginalis testis.- - - - - - - - - - ranking = 1.1666666666667keywords = tunica (Clic here for more details about this article) |
5/24. Malignant mesothelioma of tunica vaginalis testis associated with long-lasting hydrocele: could hydrocele be an etiological factor?A case of malign mesothelioma of tunica vaginalis testis in a 67 year old man with a 30 year history of hydrocele was reported. The diagnosis was made with an excisional biopsy performed in scrotal exploration and revealed epithelial type mesothelioma. High orchiectomy with hemiscrotectomy was performed. The patient had a local recurrence at the end of two years. As there were no distant metastasis only local excision was performed. In his sixth month after the second surgery he is still tumor free.

6/24. Malignant mesothelioma of testicular tunica vaginalis.We report here a case with malignant mesothelioma of testicular tunica vaginalis. An 81-year-old Japanese man with left hydrocele was referred for operation. When hydrocelectomy was performed, a thick wall of tunica vaginalis without malignancy was observed. Seven months after hydrocelectomy, a hard irregular mass was noticed in the left scrotum, therefore inguinal orchiectomy was performed. Pathologically, the mass showed severe atypia and mitosis. The diagnosis of malignant mesothelioma was made. He refused any adjuvant treatment and died 1 year later from multiple metastases to the paraaortic lymph nodes and lumbar supine.- - - - - - - - - - ranking = 1keywords = tunica (Clic here for more details about this article) |
7/24. meconium granulomas of the tunica vaginalis.meconium peritonitis results from perforation of the gastrointestinal tract during fetal life. Involvement of the tunica vaginalis may be the sole presenting clinical manifestation of the disease in the unusual event of the gut perforation resolving spontaneously. In such instances radiologically detectable calcification in the abdomen and scrotum is an essential diagnostic point. A case is described in which a baby had hydroceles and bilateral intrascrotal nodules but in which calcification was radiologically undetectable, presumably owing to its having undergon resolution. The typical histology of the nodules provided the diagnosis in this otherwise clinically undiagnostic case.- - - - - - - - - - ranking = 0.83333333333333keywords = tunica (Clic here for more details about this article) |
8/24. Well differentiated (benign) papillary mesothelioma of the tunica vaginalis.An unusual mesothelial lesion occurred in the tunica vaginalis of the testis. It conformed histologically and immunohistochemically to well differentiated papillary mesothelioma of the peritoneum. Its aetiology remains uncertain, but this lesion, more than likely, is innocuous. It is important to recognise this entity, which is not well documented in the tunica vaginalis, because it may be misdiagnosed as a malignant mesothelioma and the patient may be subjected to unnecessary treatment.- - - - - - - - - - ranking = 1keywords = tunica (Clic here for more details about this article) |
9/24. Malignant mesothelioma of the tunica vaginalis testis: a case with a predominant sarcomatous component.We present a case of malignant mesothelioma (MM) of the tunica vaginalis testis. A 64-year-old man was referred for an operation on a right hydrocele that later proved to be a tumor during surgery. The tumor was malignant with a biphasic pattern of epithelial and sarcomatous components. The latter component was predominant. Cuboidal or columnar cells formed irregular tubular structures in the epithelial component. In contrast, spindle-shaped or polygonal cells formed intricate structures with stromal connective tissues in the sarcomatous component. Immunohistochemical staining revealed that the tumor was mesothelial in origin and positive for cytokeratin, vimentin, HBME-1 antigen and calretinin. In general, MM occur in the pleura or peritoneum; those originating in the tunica vaginalis testis are very rare and represent less than 5% of all MM. In addition, MM in the tissues usually consist primarily of an epithelial component. According to previous reports tumors with a predominant sarcomatous component are extremely rare. In general, a sarcomatous component predicts poor prognosis and our case does, in fact, deteriorate over time. Our case suggests that despite its low incidence, MM must be considered when a case is diagnosed as hydrocele testicle.- - - - - - - - - - ranking = 1keywords = tunica (Clic here for more details about this article) |
10/24. rhabdomyosarcoma of tunica vaginalis masquerading as hydrocele.Paratesticular rhabdomyosarcomas are rare tumors with aggressive growth patterns. Multimodal therapy with surgery, chemotherapy, and radiotherapy provides the patient with an excellent long-term prognosis. These tumors often present in the first two decades after birth. We report on the case of an 18-year-old man with a paratesticular rhabdomyosarcoma.- - - - - - - - - - ranking = 0.66666666666667keywords = tunica (Clic here for more details about this article) |
